NON-REFILLABLE BOTTLE.

Specification of Letters Patent.

Application filed .T une 21, 1916. Serial N o. 105,031.

To all whom t may concern.'

Be it known that I, SOLOMON NARUNSKY, a citizen of the United States,residing at Baltimore city, State of Maryland, have invented certain newand useful Improvements in Non-Refillable Bottles, of which thefollowing is a specification.

This invention relates to non-reflllable bottles having a valve which isso constructed and arranged that while it permits the free flow of theliquid from the bottle, it seats if an attempt is made to force anyliquid back into the bottle, thereby preventing unscrupulous dealersfrom refilling of the bottle after it has been emptied.

The invention has for its object to provide a simple, inexpensive andhighly eiiicient valve mechanism of the kind stated, and one which canbe easily applied to the bottle.

With the object stated in view, the invention consists in a novelcombination and arrangement of parts to be hereinafter described andclaimed, and in order that the same may be better understood, referenceis had to the accompanying drawing forming a part of this specification.

In the drawing, Figure 1 is a vertical section of the valve mechanismpositioned within the bottle neck, and Figs. 2 to 5 are respectivelyperspective views of the valveguard, valve-weight and guide, valve, anddetachable valve-seat detached.

Referring specifically to the drawing, 9 denotes the neck of an ordinaryglass bottle formed with an internal annular shoulder 10 which serves asa seat for the valve mechanism, and some distance above this shoulder isan internal annular groove 11 designed to receive a retaining device forthe valve mechanism.

The valve mechanism comprises the following parts:

In the neck 9 of the bottle is mounted a cylindrical pouring tube 12having its lower end threaded to receive a detachable plug 13 providedwith a Huid passageway 14 opening at one end into the bottle and at theother end into the tube 12. |The end of the plug 13 which extends intothe tube 12 forms a seat for a valve 15, said seat having an annularraised portion 16 over which the valve seats, the latter having a bottomrecess in which the raised portion fits when the valve is seated, and inthis position of the valve it closes the upper end of the passageway 14opening into the tube. The part 16 centers the valve on its seat. On theside of the valve body are longitudinal ribs 17 which space the samefrom the inner surface of the tube 12 so that the liquid may flow pastthe valve when it is unseated and the bottle is inverted. From the backor top of the valve rises an integral stem 18 on which is slidablymounted a sleeve-like member 19 having outstanding longitudinal ribs 2Oon its outer surface. The base of this member is enlarged, and Seats onthe top of the valve 15 when the latter is seated. The opening 22 of themember 19 tapers upward, as shown in Fig. 1, and it is rabbeted at itslower end to seat on a shoulder 23 on the top of the valve. The lengthof the stem 18 is such that it projects above the member '19 when thelatter and the valve are seated. The diameter of the member 19 is suchthat the liquid can flow past the same.

Above the valve stem 18, the tube 12 incloses a valve guard 24 having atthe bottom a central cavity 25 to seat on the upper end of the valvestem, and a top central cavity 26. The guard has ribs 27 on its sidewhich project a short distance from the ends thereo Above the guard 24,the tube 12 is contracted as shown at 28 so that its inside diameter ishere less than the diameter of the guard, whereby the latter isprevented from slipping out of the tube. The contracted end of the tubeforms an external shoulder thereon on which seats an encir clingretaining ring 29 which extends into the groove 11, with a washer 30interposed between the shoulder and the ring, the latter thus serving tohold the tube 12 in the bottle-neck 9. The lower end of the tube is heldby the plug 13 which seats on the internal shoulder 10 of the bottleneck 9. Between the plug and the lower end of the tube is located awasher 31.

When the bottle is in upright position, the valve 15 closes the same byseating over the upper end of the passageway 14, and it is held closedby the member 19 seating on the valve, and the member 24 seating on thevalve stem, as sho-wn in Fig. 1. Wfhen the liquid is to be poured fromthe bottle, the latter is tilted as usual, whereupon the valve PatentedMay 29, 191V?.

15 and the parts carried thereby slide up- 11G ward in the tube 12,opening the passageway 111 into the tube. The tilting of the bottlecauses the guard 24: to drop sidewise in the neck and its weight uponthe tip end of the valve stem has a tendency of slightly tilting saidvalve from its seat to overcome any adhesive condition due to thestickiness of the fluid. rlhe liquid can now enter the tube, and itflows past the valve and the members 19 and 2li, and is discharged fromthe tube through the contracted end 9.8 thereof. Upon placing the bottleagain in upright position, the valve is at once rescated, and the parts19 and 211 follow the same and again assume the position shown inFig. 1. rllhe top pro` jecting ends of the ribs 27 space the member 211from the contracted outlet end of the tube when the valve is open, andthus serve to prevent said member from obstructing the free flow of theliquid from the tube. rl'Che member 19 gives the valve sufficient weightto cause a quick closing movement, and it also serves to guide the valveto its seat. The guard member 211 effectually prevents the insertion ofa wire or other device for holding the valve off its seat, thusfrustrating any attempt to refill the bottle. An attempt to force liquidinto the bottle while it is tilted and the valve is off its seat willcause the same to be seated at once as the member 24 would press againstthe valve stem 18 and thus force the valve Copies of this patent may beobtained for to its seat. The member 19 would also do this if any liquidshould happen to get past the member 211.

The valve mechanism may be made of glass, its parts are few and simple,and they can be easily assembled, this being done 'before the plug 13 isapplied and the tube 12 is positioned in the bottle neck 9.

.l claim:

rlhe combination with the neck of a bottlc, of a pouring tube havingopen ends and a contracted upper end forming an external shoulder, avalve-seat plug having a central aperture detachably connected to thelower end of said tube, a valve in the tube adapted te engage saidvalve-seat and provided with a rigid upwardly extending stem, a weighton said valve encircling said stem, a valve-guard loosely seated on thetop of the end of said stem below said contracted end of the tube andprovided with vertical ribs on its outer side and which project abovethe body-portion of said guard, and a clamping means engaging saidexternal shoulder on the tube and the interior of the bottle neck forlocking the tube in position.

In testimony whereof l a'tX my signature in the presence of twowitnesses.
